Description

Test rod device for forklift driver real-operation test judgment

Technical Field

The utility model relates to a fork truck examination judges the field, specifically is a fork truck driver's examination is in fact practised and is judged with examination pole device.

Background

However, the number of people for forklift driver examination is large nowadays, if the mode of on-site manual scoring of the examiner is adopted, the efficiency of forklift examination and assessment is seriously affected, the personal safety of the forklift examiner is threatened, and a great amount of manpower and financial resources are wasted. Therefore, the fork truck driver needs to practice the examination and judge and replace the manual judgment with the hanging rod device, and the currently used examination and judge device (the authorized notice number CN 215679777U) is favorable for judging the change of the inclination angle of the hanging rod.

An examination judging device (authorized bulletin number CN 215679777U) works as shown in fig. 1: an angle sensor B is fixed on the suspender, for example, when the angle sensor detects that the angle change of the suspender (the included angle between the suspender and the vertical direction) exceeds 5 degrees and is not more than 28 degrees, the intelligent examination system judges that the suspender is a wiping rod, and buckles 10 minutes each time according to an examination grading rule; if the angle of the boom 10 is greater than 28 degrees by the forklift, the intelligent examination system judges that the boom is reversed, and according to the examination scoring rule, the examinee is directly judged to be unqualified.

As shown in fig. 1: these angles are determined by the angle a of the boom with respect to the vertical upward direction. For example, the upper part of the test rod is collided by the vehicle, the test rod is horizontally moved leftwards by D cm, and the test rod is offset by an angle D degrees; assuming that the vehicle collides with the lower part of the test rod, the test rod is horizontally moved leftwards by d cm, and the test rod is offset by an angle of C degrees. It is apparent that: in the mode, when the different positions of the examination rod horizontally move by the same distance, the sensor B is provided with different measuring deflection angles, so that the accuracy of examination evaluation is affected. Based on this, there is a need for a test stick device for evaluating forklift tests in an economical, efficient, safe and accurate manner.

Disclosure of Invention

In order to overcome the defects, the utility model provides the test rod device for the forklift driver practical operation test judgment.

The technical scheme who adopts in this practicality is as follows:

a lifting rod device for forklift driver practical operation examination judgment comprises a shell, a disc, a fixed rod and a test rod; a limiting round hole is formed below the round shell, a plurality of balls are embedded in the upper surface and the lower surface of the round disc, and the balls are in rolling connection with the round disc; the disc is inside the casing, and the casing passes through ball sliding connection with the disc inner wall, and the lateral wall evenly distributed of disc has a plurality of spring, the one end fixed connection of lateral wall and the spring of disc, the other end and the inside wall fixed connection of casing of spring, the below perpendicular fixed with the dead lever of disc, the dead lever has the pole of examining in spacing round hole in the below of dead lever, dead lever and examination pole upper portion fixed connection.

The examination rod is made of elastic materials. The test rod is provided with a displacement sensor.

The beneficial effects are that:

it is assumed that when the vehicle collides with different positions of the test rod from the track, the test rod can be horizontally moved by the same distance, so that the distance from the track is accurately measured, and the phenomenon that the test rod device has measurement result deviation mentioned in the background can not occur.

The distance that the test rod moves vertically on the ground is measured by a displacement sensor, and the measurement result is uploaded to the test system. The utility model protects only the mechanical structure part. The maximum distance that the test rod can vertically move is qualified, the maximum distance that the test rod can vertically move is the radius of the round hole, and the test rod becomes a bending state once the vertical movement distance of the test rod exceeds the length of the radius of the round hole and is unqualified.

Fig. 2 is a schematic structural view of the present utility model.

Fig. 3 is a partial schematic view of the present utility model.

Fig. 4 is a cross-sectional view of fig. 2.

In the figure: 1. the device comprises a shell, 2, a disc, 3, balls, 4, a spring, 5, a fixed rod, 6, a test rod, 7, a limiting round hole, 8 and a displacement sensor.

Detailed Description

As shown in connection with fig. 2-4: the utility model comprises a shell 1, a disc 2, a fixed rod 5 and a test rod 6, wherein the top of the shell 1 can be fixed on the upper part of a roof of an indoor examination room or the upper part of a fixing device, and in order to enable the test rod 6 to be in a vertical state, the shell 1 can also be fixed on the ground, and the test rod 6 can be in a vertical ground state.

The circular shell 1 is internally provided with a disc 2, the upper surface and the lower surface of the disc 2 are respectively embedded with a ball 3, the disc 2 can move in the horizontal direction in the shell 1 through the balls 3, the balls 3 are embedded in the upper surface and the lower surface of the disc 2, the balls 3 rotate or roll on the upper surface and the lower surface of the disc 2, the balls 3 are in contact with the inner wall of the disc 2, and the shell 1 is in sliding connection with the inner wall of the disc 2 through the balls 3; four symmetrical springs 4 can be arranged on the side face of the disc 2, the disc 2 is fixedly connected with one end of the four springs 4, the other end of the springs 4 is fixedly connected with the inner side wall of the shell 1, and the four springs 4 are in a normal natural state; when the vehicle collides with the test rod 6, the test rod 6 can move vertically on the ground, the test rod 6 moves to drive the disc 2 to horizontally move, when the fixed rod 5 moves to the inner wall of the limiting round hole 7, the fixed rod 5 stops moving due to the limitation of the round hole 7, the test rod 6 is made of elastic materials, the test rod 6 can be bent, and the test rod 6 does not move vertically on the ground any more. When the vehicle breaks away from the test rod 6, the spring 4 can reset the disc 2, and the reset of the disc 2 can reset the test rod 6.
